ABSTRACT

Neural network-based solutions are under development to alleviate physicians from the tedious task of small-bowel capsule endoscopy reviewing. Computer-assisted detection is a critical step, aiming to reduce reading times while maintaining accuracy. Weakly supervised solutions have shown promising results; however, video-level evaluations are scarce, and no prospective studies have been conducted yet. Automated characterization (in terms of diagnosis and pertinence) by supervised machine learning solutions is the next step. It relies on large, thoroughly labeled databases, for which preliminary "ground truth" definitions by experts are of tremendous importance. Other developments are under ways, to assist physicians in localizing anatomical landmarks and findings in the small bowel, in measuring lesions, and in rating bowel cleanliness. It is still questioned whether artificial intelligence will enter the market with proprietary, built-in or plug-in software, or with a universal cloud-based service, and how it will be accepted by physicians and patients.

ABSTRACT

INTRODUCTION: Capsule endoscopy (CE) is an established modality in the diagnostic algorithm of small bowel (SB) pathology. Its use has expanded for investigation of upper and lower gastrointestinal diseases with similar prototypes. AREAS COVERED: This review covers the role and recent advances of CE, as a non-invasive investigative tool. EXPERT OPINION: The use of upper gastrointestinal CE is useful in patients who require surveillance for varices particularly in the current era of the COVID-19 pandemic. It has also shown high accuracy in the detection of upper gastrointestinal hemorrhage in patients presenting with a suspicion of hemorrhage. Findings on CE help to guide further management by device-assisted enteroscopy. The data on colon CE suggest comparable diagnostic accuracy to colonoscopy for polyp detection; however, more evidence is required in the high-risk group. Crohn's CE has become an integral part of the management of patients with Crohn's disease offering a comparative assessment tool post escalation of therapy. Artificial intelligence within CE has demonstrated similar if not better diagnostic yield compared to the human with a significantly shorter reading time. Artificial intelligence is likely to be in-built within CE reading platforms over the next few years minimizing reporting time and human error.

ABSTRACT

PURPOSE OF REVIEW: Upper gastrointestinal bleeding (UGIB) is a common and life-threatening condition in the United States and worldwide. RECENT FINDINGS: There have been several exciting recent advances in the endoscopic management of UGIB. One such advance is the recent approval of Hemospray by US Food and Drug Administration in May 2018. Another one is the emerging role of video capsule endoscopy as a triage and localization tool for UGIB patients. Finally, the development of new reversal agents for antithrombotic medications is an important advance in the management of life-threatening upper gastrointestinal bleed. SUMMARY: In this article, we will broadly review the management of nonvariceal UGIB, focusing primarily on the data addressing these new advances.

ABSTRACT

Magnetically controlled capsule gastroscopy (MCCG) is a novel system primarily used for the diagnosis of gastric disease. It consists of an endoscopic capsule with magnetic material inside, external guidance magnet equipment, data recorder and computer workstation. Several clinical trials have demonstrated that MCCG is comparable in accuracy in diagnosing gastric focal disease when compared to conventional gastroscopy. Further clinical studies are needed to test the diagnostic accuracy and improve the functioning of MCCG. This novel MCCG system could be a promising alternative for screening for gastric diseases, with the advantages of no anesthesia required, comfort and high acceptance across populations.

ABSTRACT

BACKGROUND: In Lombardia, one of the 20 Italian administrative Regions, small-bowel capsule endoscopy (SBCE) was introduced in 2001. In January 2011, the Regional Health Authorities established a reimbursement for outpatient SBCE. AIM: To prospectively record data on SBCE between 2011-2013 and compare them to similar data retrospectively collected from the same geographical area (covering the period 2001-2008) and published in 2008. METHODS: Consecutive SBCEs performed between January 2011 and December 2013 in Lombardia were prospectively collected. RESULTS: In 3 years, 3142 SBCEs were collected; the diagnostic yield (DY) and the overall complication rate were 48.4 and 0.9%, respectively. The main indication was suspected small-bowel bleeding (76.6% of patients); complete small-bowel inspection was achieved in 2796 (89.0%) patients. SBCE was performed as an outpatient procedure in 1945 patients (61.9%). A significant increase in the rate of patients undergoing SBCE for suspected small-bowel bleeding was observed from 2001-2008 to 2011-2013 (67.3 vs. 76.1%; p < 0.001). There was an increase in the number of complete small-bowel examinations (81.2 vs. 89.0%; p < 0.001) and of outpatient SBCEs (6.7 vs. 61.9%; p < 0.001). Conversely, both the retention rate (2.1 vs. 0.8%; p < 0.001) and the rate of patients undergoing SBCE for Crohn's disease (11.5 vs. 5.5%; p < 0.001) decreased significantly. The overall DY remained stable (50.6 vs. 48.4%; p = 0.089). CONCLUSION: Our study shows that, over 13 years, the SBCE safety profile and completion rate significantly improved over time; a change in the spectrum of clinical indications was also observed.

ABSTRACT

AIM: To compare the findings and completion rate of PillCam® SB2 and SB3. METHODS: This was a retrospective single-center study that included 357 consecutive small bowel capsule endoscopies (SBCE), 173 SB2 and 184 SB3. The data collected included age, gender, capsule type (PillCam® SB2 or SB3), quality of bowel preparation, completion of the examination, gastric and small bowel transit time, small bowel findings, findings in segments other than the small bowel and the detection of specific anatomical markers, such as the Z line and papilla. RESULTS: The mean age of the patients was 48 years and 66.9% were female. The two main indications were suspicion/staging of inflammatory bowel disease (IBD) and obscure gastrointestinal bleeding (OGIB) (43.7% and 40.3%, respectively). Endoscopic findings were reported in 76.2% of examinations and 53.5% were relevant findings. No significant differences were found between SB2 and SB3 with regard to completion rate (93.6% vs 96.2%, p = 0.27), overall endoscopic findings (73.4% vs 78.8%, p = 0.23), relevant findings (54.3% vs 52.7%, p = 0.76), first tertile findings (43.9% vs 48.9%, p = 0.35), extra-SB findings (23.7% vs 17.3%, p = 0.14), Z line and papilla detection rate (35.9% vs 35.7%, p = 0.97 and 27.1% vs 32.6%, p = 0.32, respectively). With regard to the patient subgroups with suspicion/staging of IBD, significant differences were found in relation to the detection of villous edema and the 3rd tertile findings, thus favoring SB3 (26.3% vs 43.8%, p = 0.02 and 47.4% vs 66.3%, p = 0.02, respectively). Mucosal atrophy was significantly more frequently diagnosed with the PillCam® SB3 in patients with anemia/OGIB (0% vs 8%, p = 0.03). CONCLUSIONS: Overall, PillCam® SB3 did not improve the diagnostic yield compared to SB2, although it improved the detection of villous atrophy and segmental edema.

ABSTRACT

Introduction: Colon capsule endoscopy (CCE) is an alternative approach for the examination of the colon in patients who refuse colonoscopy or after incomplete colonoscopy (IC). We conducted a study to determine the frequency of complete colonoscopy after IC, the diagnostic yield of CCE, the therapeutic impact of lesions found in CCE, the level of colon cleanliness and the safety of the procedure. Methods: We performed a prospective, multicenter study involving ten Spanish hospitals. Consecutive outpatients aged ≥ 18 years with previous IC were invited to participate. The latest version of the CCE device, PillCam(TM) COLON 2 (CCE-2), was administered to all patients according to the protocol. Results: The study population comprised 96 patients. The most frequent cause of IC was the inability to move past a loop using standard maneuvers (75/96 patients, 78%). Complete visualization of the colon was obtained with CCE-2 in 69 patients (71.9%). Of the 27 patients in whom the CCE-2 did not reach the hemorrhoidal plexus, it passed the colonic segment explored with the previous colonoscopy in 20 cases; therefore, it could be inferred that a combined approach (CCE-2 plus colonoscopy) enabled complete visualization of the colonic mucosa in 92.7% of patients. CCE-2 revealed new lesions in 58 patients (60.4%). Polyps were the most frequent finding (41 patients; 42.7% of the total number of patients). In 43 of the 58 patients (44.8% of the total number of patients), the new lesions observed led to modification of therapy, which included a new colonoscopy for polyp resection or surgery in patients with colonic neoplasm. Conclusions: CCE-2 is a suitable diagnostic procedure that can lead to more frequent diagnosis of significant colonic lesions after IC (AU)

ABSTRACT

INTRODUCCIÓN: el uso de la enteroscopia con videocápsula fue aprobado por la FDA en 2001. La hemorragia digestiva y la enfermedad inflamatoria intestinal son sus principales indicaciones. En nuestro centro se realiza desde 2004. MATERIAL Y MÉTODOS: Hemos recogido de forma retrospectiva los pacientes tratados mediante cápsula de intestino delgado desde octubre de 2004 hasta abril de 2015. Las indicaciones se han dividido en grupos: hemorragia digestiva de origen oscuro, tanto oculta como manifiesta; enfermedad inflamatoria intestinal; otras indicaciones. Los hallazgos se han dividido: lesiones vasculares; lesiones inflamatorias; otras lesiones; estudios normales; estudios no concluyentes. RESULTADOS: De un total de 1.291 estudios se ha incluido 1.027 en el análisis. La edad media es 56,45 años, con 471 hombres y 556 mujeres. La enfermedad más frecuentemente observada fueron las lesiones vasculares, asociadas o no a otras lesiones. Cuando la indicación era una hemorragia digestiva, el impacto diagnóstico fue del 80%. En la enfermedad inflamatoria esta cifra solo alcanza el 50%. El rendimiento diagnóstico es mucho menor en el grupo de «otras indicaciones». No se han registrado complicaciones mayores. DISCUSIÓN: La cápsula de intestino delgado tiene un alto rendimiento diagnóstico en los casos de hemorragia digestiva; el número de estudios con hallazgos positivos es menor en los de enfermedad inflamatoria intestinal. CONCLUSIONES: Se trata de una modalidad diagnóstica segura y de gran utilidad para el diagnóstico de enfermedad del intestino delgado, aunque se precisa mejorar el índice de sospecha en la enfermedad inflamatoria intestinal


INTRODUCTION: Capsule endoscopy was approved by the FDA in 2001. Gastrointestinal bleeding and inflammatory bowel disease are the main indications. It has been available in our hospital since 2004. METHODS: We retrospectively analysed data from patients who underwent small bowel capsule endoscopy in our hospital from October 2004 to April 2015. Indications were divided into: Obscure gastrointestinal bleeding (occult and overt), inflammatory bowel disease, and other indications. Findings were divided into: Vascular lesions, inflammatory lesions, other lesions, normal studies, and inconclusive studies. RESULTS: A total of 1027 out of 1291 small bowel studies were included. Mean patient age was 56.45 years; 471 were men and 556 women. The most common lesion observed was angiectasia, as an isolated finding or associated with other lesions. Findings were significant in up to 80% of studies when the indication was gastrointestinal bleeding, but in only 50% of studies in inflammatory bowel disease. Diagnostic yield was low in the group «other indications». No major complications were reported. DISCUSSION: Small bowel capsule endoscopy has high diagnostic yield in patients with gastrointestinal bleeding, but yield is lower in patients with inflammatory bowel disease. CONCLUSIONS: Our experience shows that capsule endoscopy is a safe and useful tool for the diagnosis of small bowel disease. The diagnostic yield of the technique in inflammatory bowel disease must be improved

ABSTRACT

Colon capsule endoscopy is a wireless and minimally invasive technique for visualization of the whole colon. With recent improvements of technical features in second-generation systems, a more important role for colon capsule endoscopy is rapidly emerging. Although several limitations and drawbacks are yet to be resolved, its usefulness as a tool for colorectal cancer screening and monitoring disease activity in inflammatory bowel diseases has become more apparent with increased use. Further investigations, including multicenter trials, are required to evaluate the substantial role of the colon capsule in managing colorectal diseases.

ABSTRACT

INTRODUCTION: Since its introduction, small bowel video capsule endoscopy (VCE) use has evolved considerably. AIM: Evaluation of the temporal changes of small bowel VCE utilization in three tertiary centers in Greece in Era 1 (2002-2009) and Era 2 (2010-2014) and the development a forecast model for future VCE use during 2015-2017. MATERIALS AND METHODS: Data from all small bowel VCE examinations were retrieved and analyzed in terms of the annual number of the performed examinations, their indications and the significance of their findings. RESULTS: Overall, we evaluated 3724 VCE examinations. The number of studies peaked in 2009 (n=595) and then decreased to reach 225 in 2014. Overall, more (53.8 vs. 51.4%) patients with iron-deficiency anemia and obscure gastrointestinal bleeding (IDA/OGIB) and fewer (10.7 vs. 14%) patients with chronic diarrhea were evaluated in Era 2 compared with Era 1 (P=0.046). In Era 2, there were more nondiagnostic examinations (39.5 vs. 29.3%, P<0.001), whereas the rate of cases with relevant findings decreased from 47.8 to 40.9%. According to the time trend analysis, we developed a forecast model with two scenarios: the pessimistic and the optimistic. Validation of the model with 2015 data showed that reality was close to the pessimistic scenario: the number of exams further decreased to 190, studies carried out for IDA/OGIB increased to 67%, and there were more negative than positive exams (40.7 vs. 39.2%). CONCLUSION: The number of VCE studies carried out after the emergence of the financial crisis decreased significantly and VCE indications were optimized. Our forecast model predicts lower numbers of VCE studies, with IDA/OGIB being the dominant indication. However, the predicted increase of negative exams requires further evaluation.

ABSTRACT

Background and aims: A computed assessment of cleansing (CAC) score was developed to objectively evaluate small-bowel cleansing in the PillCam capsule endoscopy (CE) system and to overcome the subjectivity and complexity of previous scoring systems. Our study aimed to adapt the CAC score to the Mirocam® ystem, evaluate its reliability with the Mirocam® CE system and compare it with three validated subjective grading scales. Patients and methods: Thirty CE were prospectively and independently reviewed by two authors who classified the degree of small-bowel cleanliness according to a quantitative index, a qualitative evaluation and an overall adequacy assessment. The authors were blinded for the CAC score of each CE, which was calculated as ([mean intensity of the red channel]/[mean intensity of the green channel] - 1) x 10. The mean intensities of the red and green channels of the small-bowel segment of the «Map View» bar in the Miroview Client® were determined using the histogram option of two photo-editing software. Results: There was a strong agreement between both CE readers for each of the three subjective scales used. The reproducibility of the CAC score was excellent and identical results were obtained with the two photo-editing software. Regarding the comparison between the CAC score and the subjective scales, there was a moderate-to-good agreement with the quantitative index, qualitative evaluation and overall adequacy assessment. Conclusions: CAC score represents an objective and feasible score in the assessment of small-bowel cleansing in the Mirocam® CE system, and could be used per se or as part of a more comprehensive score (AU)

ABSTRACT

La enfermedad de Whipple es una infección sistémica crónica producida por el actinomiceto Tropheryma whipplei. Las pruebas endoscópicas son claves en el diagnóstico ya que permiten la toma de biopsia y su estudio anatomopatológico para el diagnóstico definitivo de esta entidad. Presentamos un caso de enfermedad de Whipple en el que la cápsula endoscópica, poco común para el diagnóstico de esta afección, fue clave para el mismo y su realización antes y después del tratamiento antibiótico permite describir la evolución macroscópica de los hallazgos en intestino delgado. Este caso ilustra la utilidad de la cápsula endoscópica al permitir un estudio completo del intestino delgado en esta enfermedad en la que hasta el 30% de los pacientes puede cursar con gastroscopia normal (AU)


Whipple´s disease is a chronic systemic infection produced by the actinomycete Tropheryma whipplei. Endoscopic tests are key in the diagnosis as they allow biopsy and histopathological examination for definitive diagnosis of this entity. We present a case of Whipple´s disease where capsule endoscopy, uncommon for the diagnosis of this condition, was essential for it and its performance before and after antibiotic treatment allows to describe the macroscopic evolution of the findings in the small bowel. This case illustrates the utility of capsule endoscopy to allow complete examination of the small bowel disease in which up to 30% of patients may present with normal endoscopy (AU)

ABSTRACT

Since its introduction into clinical practice 15 years ago, capsule endoscopy (CE) has become the first-line investigation procedure in some small bowel pathologies, and more recently, dedicated esophageal and colon CE have expanded the fields of application to include the upper and lower gastrointestinal disorders. During this time, CE has become increasingly popular among gastroenterologists, with more than 2 million capsule examinations performed worldwide, and nearly 3000 PubMed-listed studies on its different aspects published. This huge interest in CE may be explained by its non-invasive nature, patient comfort, safety, and access to anatomical regions unattainable via conventional endoscopy. However, CE has several limitations which impede its wider clinical applications, including the lack of therapeutic capabilities, inability to obtain biopsies and control its locomotion. Several research groups are currently working to overcome these limitations, while novel devices able to control capsule movement, obtain high quality images, insufflate the gut lumen, perform chromoendoscopy, biopsy of suspect lesions, or even deliver targeted drugs directly to specific sites are under development. Overlooking current limitations, especially as some of them have already been successfully surmounted, and based on the tremendous progress in technology, it is expected that, by the end of next 15 years, CE able to perform both diagnostic and therapeutic procedures will remain the major form of digestive endoscopy. This review summarizes the literature that prognosticates about the future developments of CE.

ABSTRACT

The review is focused on recent publications concerning examination of patients with gastroenterological pathology and the use of capsule endoscopy for diagnostics ofsmall bowel diseases. It is shown that radiological methods and enteroscopy are second line diagnostic tools while capsule endoscopy becomes the method ofchoice for the detection of latent gastrointestinal bleeding, tumours, Crohn's disease, and other enteropathies. The advantages of capsule enteroscopy include high effectiveness, atraumaticity, low frequency of complications and possibility to conduct studies without anesthesia. Much attention is given to indications and contraindicationsfor capsule endoscopy and methods of patient preparationfor this procedure.

ABSTRACT

Currently, the major problem of all existing commercial capsule devices is the lack of control of movement. In the future, with an interface application, the clinician will be able to stop and direct the device into points of interest for detailed inspection/diagnosis, and therapy delivery. This editorial presents current commercially-available new designs, European projects and delivery capsule and gives an overview of the progress required and progress that will be achieved -according to the opinion of the authors- in the next 5 year leading to 2020.

ABSTRACT

Consensuses on fellowship training in wireless capsule endoscopy (WCE) interpretation have been published for adult gastroenterology (GI) but not in pediatric GI training. A questionnaire has been sent to 64 pediatric and 45 adult GI fellowship programs to compare their present training approach. Adult GI programs reported having a formal GI capsule endoscopy module in 38% and required to attend hands-on course in 27% as compared with 4% and 8% in pediatric programs, respectively. A more formalized approach to WCE training may be required for credentialing pediatric trainees to be aligned with expectations in adult GI programs.

ABSTRACT

Video capsule endoscopy (VCE) has revolutionized the diagnostic work-up in the field of small bowel diseases. Furthermore, VCE has the potential to become the leading screening technique for the entire gastrointestinal tract. Computational methods that can be implemented in software can enhance the diagnostic yield of VCE both in terms of efficiency and diagnostic accuracy. Since the appearance of the first capsule endoscope in clinical practice in 2001, information technology (IT) research groups have proposed a variety of such methods, including algorithms for detecting haemorrhage and lesions, reducing the reviewing time, localizing the capsule or lesion, assessing intestinal motility, enhancing the video quality and managing the data. Even though research is prolific (as measured by publication activity), the progress made during the past 5 years can only be considered as marginal with respect to clinically significant outcomes. One thing is clear-parallel pathways of medical and IT scientists exist, each publishing in their own area, but where do these research pathways meet? Could the proposed IT plans have any clinical effect and do clinicians really understand the limitations of VCE software? In this Review, we present an in-depth critical analysis that aims to inspire and align the agendas of the two scientific groups.
